"But what can I do with it?"

Basically, anything. The software lets you build your own unique gestures into a whole heap of apps and programs. Photoshop designer? Use your hand to adjust values, add layers, undo actions, save files - all without interacting with a mouse or keyboard.

Every conceivable hand action, from flicking to swiping to spinning, or even making specific shapes with your hands ("Bullhorns" for "save"?), can be assigned to a shortcut or action.

The Gest controllers are so sensitive they can even be used to type - though your touch typing skills will have to be on point. Autocorrect options will make the best guess of what you're attempting to say, but we can't imagine this will be any faster than using a conventional keyboard.

Currently seeking funding via a Kickstarter project, Gest is expected to ship in November 2016. You can put an order in now for a single controller at around £100.
